In the course of our screening program using an in situ SUMOylation-detecting system, kerriamycin B, which had been originally isolated as an antibiotic, was identified as a novel inhibitor of protein SUMOylation. Kerriamycin B inhibits both in vitro and in vivo protein SUMOylation by blocking the formation of the E1-SUMO intermediate. Our findings will provide not only a novel tool for investigating the role of SUMO conjugations but also useful information for developing therapeutic drugs., text, application/pdf}, pages = {221--224}, title = {Kerriamycin B inhibits protein SUMOylation}, volume = {62}, year = {2009}, yomi = {オサダ, ヒロユキ and ヨシダ, ミノル} }
